Kick leg cart luck 貴唔貴過支臂？

玩肛多過玩臂.....haha!

其實尼支氣臂係吾係解決左一般套管式氣臂的很多問題呢?
我好喜歡這氣臂,又吾貴又易保養.
最好找 Daiwok來講下

大師，果條鋁角唱臂好型啊！
唱嘢掂唔掂呀？

====================================

Penndan - thanks for the mention.

There are differences in the engineering for high pressure and low pressure tonearms. This governs how you should tweak and tame the air pressure. If you are using high pressure tonearm ( I am talking Rockport / Kuzma Airline 35 PSI and above !), then your pressure flow is different. Your pressure is maintained at high pressure low flow as the bearing is an air bushing and it is not designed for high volume of air flow, in fact the air being released is very very low and expect the air compressor to switch on every fews hours not much more depending on the size of you air tank.

Now for low pressure arms such as the Terminator / Conductor / MG1 these you need high air flow but low pressure. I am talking 5 PSI and lower and as low as 1.5 PSI. These arms you need a nice big surge tank, but flow is constant. You will not hear any hissing or any noise if you get he air flow correct. Remember you do not have an air bushing, you have a manifold and this is constantly leaking air, but the air required for the air cushion on the wand is not as much as you think and the lower the air pressure the lower the resonance. You need to understand Paul Ladegaard's design. In fact the Conductor is based on the Dennesen design which I also have,and this is also true on the Forsell tonearm. These all have manifolds and not air bushings. So what is a good pump to use ? actually I am using an Hi Blow Japanese Gold fish Pond pump, but I have gone for a bigger capcity 40 liter / min, but a 20 liter / min is suffice, I have this step down by a 110V transformer to reduce the motor vibrations running the pump at half capacity, then I have 2 surge tanks, one big one (probably a 50 gallon tank) and one small one before entering the tonearm. Always have the valve control for air flow before the surge tank as valves cause air flow turbulence, you should be able to dial in the right air pressure from here. How can you tell you have the right air pressure ? dial the air pressure until the cartridge starts to skip, now turn pressure up. You will need to turn this pressure up until the cartridge starts tracking normally again, you will need to do this a few times as the wand travels along the manifold, depending on how your arm is designed, some manifolds have less air towards the center of the record, hence the air pressure needs to be increased if the cartridge skips again.

Moreover, linear tracking arms are super sensitive to VTA, this is because the majority of them have shorter wands, so do check and do tweak and have fun. If anyone tells you that these arm do not have dynamics and bass, they have not setup an air bearing arm properly IMHO.

I hope the above is useful to you guys.

上了一課
Thanks Daiwok !!

即係我要用番HI-BLOW個泵先arm
不過依家把聲幾定吓又唔差
玩一排先再轉番未遲!

配料用係支臂度约三千大洋
當然臂貴啦!

明天自由打

try and step down the voltage on the Hi Blow, this will reduce the pump noise.

帶張輪椅比你lol

終於出到聲，
啱啱開波，
聽多幾隻碟睇下點先。

帶埋地拖喇！

留來自用啦!
邊度跌低,就要係邊度再站翻起...ha.ha....

我用緊高壓泵玩低壓臂
